asp.net-mvc-3 - 将多个值传递给 ActionResult

Question

我在 mvc 3 razor 中有这段代码

@using (Html.BeginForm("MyAction", "MyController"))
{
    <input type="text" id="txt" name="txt"/>          
    <input type="image" src="image.gif" alt="" />
}   

在 Controller 中我有这个代码

[HttpPost]
public ActionResult MyAction(string text)
{
    //TODO something with text and return value...
}

现在，如何发送一个新值，例如 id 到 Action 结果？？？谢谢

Answer 1

您使用 View 模型:

public class MyViewModel
{
    public string Text { get; set; }

    // some other properties that you want to work with in your view ...
}

然后将此 View 模型传递给 View :

public ActionResult MyAction()
{
    var model = new MyViewModel();
    model.Text = "foo bar";
    return View(model);
}

[HttpPost]
public ActionResult MyAction(MyViewModel model)
{
    // remove the Text property from the ModelState if you intend
    // to modify it in the POST controller action or HTML helpers will
    // use the old value
    ModelState.Remove("Text");
    model.Text = "some new value";
    return View(model);
}

然后 View 被强类型化为这个模型:

@model MyViewModel

@using (Html.BeginForm("MyAction", "MyController"))
{
    @Html.EditorFor(x => x.Text)
    <input type="image" src="image.gif" alt="" />
}
